BOX OR CARTON Filed June 9, 1934 2 Sheets-Sheet 2 INVENTOR CL/FFORD .lA40/VCE,

lPatented Nov. 2, 1937 My present invention relates to boxes or cartonsmade of fibrous material, such as double faced kraft board, and.' moreparticularly to an improved box or carton made from a single blank ofmaterial.

In fabricating boxes or cartons from sheet material, such as paper,kraft board, or the like, it is desirable that the blank from which thebox or carton be made, should be as nearly rectangular as possible, inorder that the waste of material be kept to a minimum. With the presentday necessity for hand holds in boxes and cartons of any considerablesize, the waste of material has increased despite the fact that arectangular blank may be used. Also, as the cutting and scoring of theblank is done by a die structure, the necessary cutting and strippingdevices for blanking out openings for hand holds has materiallyincreased the cost of the boxes or cartons, besides materially slowingdown the production thereof.

In my present invention, I have obviated the objections to prior methodsof manufacturing boxes or cartons, and have succeeded in making a box orcarton of pliable fibrous material, such as double-faced kraft board,from a rectangular blank, and cut and score the blank by a simple die,and avoid entirely the necessity of any cutout portion that wouldrequire blanking out and stripping devices as a part of or accessory to,the die structure.

In carrying out my invention, I utilize a rec tangular blank, cut andscored to define the various elements of a box or carton, and by foldingthe various elements into proper position and 35 relation to each other,produce a box or carton in which the sides and ends thereof are doublereinforced, and in which hand holds are automatically formed by foldingreinforce elements into engagement with the ends of the box, and whichelements interengage with themselves and with the reinforce for thesides of the box or carton, to thereby prevent displacement regardlessof the load within the box or carton.

An object of my invention therefore, is an improved box or carton madefrom a blank of fibrous material.

Another object of my invention is an improved box or carton made from ablank of sheet material and having a hand hold formed therein during theassembling thereof.

Still another object is an improved box or carton made from a blank ofsheet material and being reinforced about its sides and ends, and inwhich the reinforcing elements are mutually interlocked.

Referring to the drawings, Ill designates a blank, made from anysuitable flexible sheet material, such as cardboard, double faced kraft20 board, and the like. Centrally located in the blank I0, whichisrectangular in form, is a box or carton bottom II, defined by the scoredlines I2, I3, I4 and I5. The bottom II may be of any desired shape, butpreferably rectangular. 25 Formed of the blank I0, and at the oppositeends of the bottom II, are the box or carton ends I6 and I1, the end I6being separated from the bottom II by the scoring I2, and the end I'Ibeing likewise separated by the scoring I4. Formed at 30 the ends of thebox or carton end I6 are wings I8 and I9, such wings being triangular inshape and divided from the end I6 by a scored line 20, in alignment withthe scored line I3, and a scored line 2|, in alignment with the scoredline I5, 3 respectively. Formed at the ends of the box or carton end I'lare wings 22 and 23, similar to the Wings I8 and I9, these wings 22 and23 being Ydivided from the end II by the scored lines 24 and 25respectively, the scored line 24 being in 40 alignment with the scoredline I3 and the scored line 25 being in alignment with the scored lineI5. f

Formed of the blank I0 and divided from the bottom I I by the scoredline I3, is a box or carton 45 side 26, of a length equal to the lengthof the bottom II, and of a Width equal to the width of the box or cartonends I6 and I'I. Formed of the blank I Il is a box or carton sidereinforce 21, divided from the box or carton side 26 by the 50 scoredline 28 which is parallel to the scored line I3. The width of thereinforce` 21 is substantially equal to that of the side 26 and thelength is slightly less than the length of the side 26. `At one end ofthe side 26 and divided therefrom by 55 2 the scored line 29 is ahandhold member 38, this member being separated from the wing I6, during thedleing operation of forming the blank I6, by a line of cut 3|. Formedintegral with the hand hold member 30 and separated therefrom by thescored line 32, is a locking member 33, this locking member being spacedapart from the endof the reinforce 21 by the cut-out 34.

At the opposite end of the side 26 is arranged the hand hold member 35,divided from the side 26 by the scored line 36, and from the wing 22 bythe line of cut '31. Integral with the hand hold member 35 and dividedtherefrom by the scored line 38 is the combined reinforcing and lockingmember 39 that is spaced from the reinforce 21 by the cut-out 40.

The arrangement of side, reinforce, handholds and locking members justdescribed is duplicated on the opposite side of the bottom II, the otherside being designated 4I, the reinforce attached thereto 42, the scoredline between the side and reinforce being 43, the handhold members beingdesignated 44 and 45 respectively, divided from the side 4| by thescored lines 46 and 41 respectively. The hand holds 44 and 45 areseparated from the wings I9 and 23 by the lines of cut 48 and 49respectively. Attached to the hand hold member 44 and divided therefromby the scored line 50 is the locking member 5|, this member being spacedfrom the end of the reinforce 42 by the cut-out 52. Attached'to the handhold member 45 and divided therefrom by the scored line .53 is thelocking member 54, this member being spaced from the end of thereinforce 42 by the cut-out 55.

In the side member 26, centrally thereof and adjacent to the scored line28, is a slot 56 through which may be passed a strap forming a handlefor the box or carton to be constructed from the' blank I8. A similarlysituated like slot 51 is formed in the side member 4I.

58 designates a strap or handle, preferablyl and may be fastened to thesides 26 and 4| by staples 59, or in any other convenient manner. Analternative type of fastener is shown in Fig. 3, where a metal clip orhook 60 is shown attached to one end of the strap 58, the hook beingadapted to engage with the lower edge of the reinforce members 21 and42.

By reference to Fig. 1 it will be noted that the blank I is rectangularand the only material wasted from the sheet of material fromwhich theblank is formed is the space adjacent to the hand hold members 30, 35,4'4 and 45, the locking members 33, 39, and 54, and the cut-outs 34, 40,52 and 55. Also, it will be noted that no portion of the blank I0necessitates the cutting out of material by a complicated die structure.The blank I0 therefore, may be produced by a simple die, withoutappreciable Waste and at a minimum cost.

Assuming the blank I8 to have been formed as above described, and thatit is desired to assemble the same into box or carton form, one of theends, as the end I1, is folded about the scored line I4 into a positionperpendicular to the bottom II, and the wing 23 is folded about thescored line 25 into a position perpendicular to the end I1, and thebottom II, as shown in Fig. 2. A similar operation is then performedwith respect to the end I6, and wing I9. The side member 4| is thenfolded about the scored line I5 into a position perpendicular to thebottom II and into engagement with the now outer faces of the wings 23and I9.

The reinforce 42 is now folded about the scored line 43 into a positionwithin the box or carton and into parallelism with the side 4|, thisoperation resulting in enclosing the wings 23 and I9 within the side 4|and reinforce 42.

Similar operations are then performed on the wings 22 and I8, the side26 and reinforce 21.

To complete the box or carton structure the hand hold members are foldedabout their respective score lines 20, 2 I, 24 and 25 to bring suchmembers into position against the outer face of the ends I6 and I1,after which the locking members 33,v 5I, 39 and 54 are folded intoposition against the inner face of the ends I6 and I1. This latteroperation is clearly shown in Fig. 3, where the locking member 54 isshown in its final position against the inner face of the end I1, andwith its outer edge locking the reinforce 42 in position. Also, thelocking member 39 is shown in Fig. 3, in position preparatory to foldinginto final position, and it will be apparent that when it is in finalposition, it will lock the reinforce 21 in its final position, and thelocking members 54 and 39 willengage with each other so as to preventaccidental displacement of the parts.

Referring again to Fig. 3, it will be noted that the hand hold members44 and 38 engage with each other to assist in holding the parts inproper position and these members cooperate to produce an eflicient handhold, the resiliency of the material, such as double-faced kraft board,readily permitting the insertion of the fingers of the hand of theoperator between the hand hold members and the outer face of the end.

There is thus produced from a rectangular blank, a. box or carton inwhich the sides and ends are reinforced, and in which hand holds, formedintegrally with the material of the box or carton, are arranged atopposite ends of the box or carton.

' Referring now to Fig. 4, there is shown in plan view a top blank, madefrom a sheet of fibrous material, preferably double-faced kraft board,and comprising a top 62, rectangular in form and of a size to make asuitable cover for the box or carton illustrated in Fig. 3. This top 62is provided at its ends with end members 63 and 64, divided from the top62 by scored lines 65 and 66 respectively. Formed integral with thematerial of the ends 63 and 64 and divided therefrom by scored lines 61and 68 respectively, are locking andreinforce members 69 and 16respectively.

On the sides of the top 62 are arranged sides 1I and 12 divided from thetop by scored lines 13 and 14 respectively. These sides 1| and 12 have iattached at their ends extensions 15 and 16 divided from the sides byscored lines 11. Centrally arranged in the top 62 and extendingtransversely thereof is a slot 18 and through which may extend the strapor handle 58. The blank from which the top is cut is rectangular inshape and no cut-outs, other than the slot 18 and the space between thesides of the extensions 15 and 16 and the ends of the sides andreinforces 63, 64 and 69 and are necessary. None of such cut-outsnecessitate the use of a stripping device on the die, and therefore, thedie is of simple character and the blank is produced rapidly and withoutwaste of material.

In forming the blank shown in Fig. 4 into the box or carton top shown inFig. 5, the sides 1| and 12 are folded on the scored lines 13 and 14respectively, into a position perpendicular to the top 62, theextensions and 16 are folded on vthe scored line`1-1 perpendicular tothe sides, after nun) which the'ends' 63 and 6l are folded on the scoredlines 65 and 66 into engagement with the extensions 'I5 and 1B. Thereinforce members 69 and I0 are then folded on the scored lines 61 and68, thus clasping the extensions 15 and 16 against the inner face of theends G3 and. respectively.

'Ihe resulting cover, when put on the box or carton shown in Fig. 3, hasthe slot 'I8 positioned over the strap or handle 58 and such handle,projecting through the slot 'I8 may be used as a means for carrying thebox or carton.

The blanks from which the box or carton and cover are made, maybe'assembled at the factory and shipped to the customer ready for use, ormay be shipped at to the customer, who may assemble them as needed.
